A TJORA/EFS' United States Patent 3,186,410 CLQSED SYSTEM'URINARYDRAINAGE SET Frank S. Buono, Garfield, N.J., assignor to Becton,Dickinson and (Zompany, East Rutherford, N.J., a corporation of NewJersey Filed Aug. 27, 1962, Ser. No. 219,495 6 Claims. (Cl. 128-275)This invention relates to a structurally and functionally improvedliquid receiving, retaining and dispensing assembly of particularutility where employed as a urinary drainage set.

It is a primary object of the invention to furnish a receptacle assemblywhich may be employed in numerous different associations, and especiallythose in which body fluids are involved. So employed, an assembly isfurnished which will be compact and the various components of which willbe connected to each other in manners such that they will not becomeaccidentally detached. Moreover, the assembly may be advantageously usedby relatively unskilled personnel, and even by a patient, withoutencountering difiiculty in such use.

A further object is that of designing a structure of primary utilitywhen employed as a closed system urinary drainage set, the setdecreasing the possibility of infection due to contamination of thedrainage bag or receptacle. Moreover, the assembly in use will effect aconsiderable saving of labor over sets as heretofore employed.

Among other objects of the invention, are those of furnishing anassembly which may readily be manufactured in accordance with quantityproduction methods and accordingly produced at minimum expense;'theassembly having a relatively long life and capable of being readilysterilizable.

With these and other objects in mind, reference is had 9 to the attachedsheets of drawings illustrating one practical embodiment of theinvention and in which:

FIG. 1 is a side elevation of the assembly;

FIG. 2 is an edge view thereof;

FIG. 3 is a plan view of the assembly;

FIGS. 4, 5, 6, 7, 8, 9 and 10 are transverse sectional views taken alongthe lines 44, 5-5, 66, 7-7, 83, -9, and *I010, and in the direction ofthe arrows as indicated in FIG. 1; and

FIG. 11 is a fragmentary sectional view taken along the line 111-1 inthe direction of the arrows as indicated in FIG. 10.

Referring primarily to FIG. 1, the numeral 20 indicates the front wallof the receptacle, which is preferably folded upon itself to provide arear wall, the edges of which register with the edges of the front wall.It is preferred to form the receptacle body of a clear plastic such asvinyl. Obviously, separate sheets could be employed to provide the frontand rear faces of the receptacle. However, as illustrated, the adjacentside edge zones at the free edges of the sheet are bonded togetherconveniently by the action of heat. Thi has been indicated at 21. Thezone defining the upper end of the receptacle is similarly bonded.Likewise, a bonding zone 23 may extend throughout at least a part of thereceptacle adjacent its lower edge. The inner face of the sheet, orsheets 20, may have a rough finish. This will prevent undesired adhesionof the receptacle layers to each other.

A drainage tube 24 has it inner end permanently bonded to a tubularportion 25 defined by the inner faces of the receptacle and communicateswith the interior thereof. Above this, the receptacle provides an airpa.- sage 26 open to the atmosphere. The outer end of drainage tube 24mounts, for example, a standard catheter adapter 27. A coupling isfurnishing between this adapter and tube conveniently by ensleeving theouter end of the 3,186,419 Patented June I, 1965 latter over its reducedend portion 28. This has been shown in FZG. 7. Also, in that view a cap29 conveniently of polyethylene has been shown as initially closing thebore of the adapter 27.

The zone of seal furnishing passage-Way 2546 has been indicated by thenumeral 30 in FIGS. 4 and 5. In the latter figure, a filter body 31 hasbeen shown in a position short of the outer end of passage 26. Thisfilter is conveniently formed of cotton and serves to filter outobjectionable bacteria as air flows through the passageway to the baginterior to equalize pressure. As shown in FIG. 6, passage 25 has itsbore conveniently deformed to provide a flange 32 against which theinner end of tube 24 abuts; the parts being subsequently adhered to eachother by heat sealing, or otherwise. A similar flange indicated at 33 inFIG. 1 may prevent filter 31 from moving iu wardly up passage 26 beyonda predetermined point.

With a view to properly supporting the bag, the upper edge zone of thelatter at a point above passageway 25-25 is provided with openings 34.Through these a cord 35 is disposed. Ahoolc member 36, including ashank, is arranged so that the cord passes through an opening of thelatter. Between the upper edge zone of the receptacle and the aperture34 a metallic stiffener rod 37 is arranged. This reinforces the assemblyand prevents a pulling out of the cord. Such a supporting arrangementwill enable carryin of the receptacle by an ambulatory patient and thesuspension of the receptacle from any convenient sup porting surfacesuch as is found at bed side.

A discharge tube 38 is integrally bonded with the bag or receptacleadjacent its lower end. (See FIG. 8.) Also, it is bonded with a tubeextension 39, the inner end of which conveniently bears against a stopflange, or head 40, forming a part of tube 38. The inner end of thetubular extension 38 is connected with the interior of the bag adjacentthe side edge opposite from that at which the downwardly inclinedsealing zone 23 is disposed. Also, the intake end of the extension isadjacent the lower edge zone of the bag. Accordingly, liquid will draininto What might be termed as a pocket of the receptacle at a pointbeyond the sealing zone 23. At the outer end of tube 39, there isprovided a preferably fitting 41,

which again is conveniently secured in position by sealing. A cap 4-2closes the outer end of this fitting. The latter is normally maintainedin the position shown in FIG. 1 by preferably providing it with anextension 43 carrying one part 44 of a snap fastener. As hown,especially in FIGS. 10 and 11, this part cooper-ates with acomplementary snap fastener portion 45 secured to the receptacle Withinthe zone 23. As also shown in FIG. 11, fitting 41 is conveniently formedwith a flange, or bead 46, against which the outer end of tube 39 abuts;the parts again being conveniently heat sealed to each other. A cutoffclamp 47, as best shown in FIG. 9, is mounted upon tube 39 and serves inconventional manner to constrict the bore of the latter and prevent aflow therethrough. Preferably, this clamp will be of the type capable ofone-hand operation.

In use, it will be apparent that if a filter plug is associated withfitting 41, thi plug will be initially removed and cap 42 applied to thefitting. The bag may now be supported as desired, by employing the hook36, or an equivalent thereof for this purpose. Drainage tube 24 will beconnected with the patient in a standard manner.

To drain the bag, a bulk collection container will ordi narily be used.This may be positioned on the floor at bed side. Thereafter, theelements of the snap cover assembly 44-45 will be detached from eachother. Cap 42 will be removed. Clamp 47 will be opened after fitting 41is disposed over the mouth of the collection container. After completingthe drainage, the clamp may again be closed, and after cleaning them-ating surfaces of fitting 41 and cap 42, the latter is seated.Following this, snap fasteners 44-45 may again be coupled to each other.

As will be understood with an assembly of this type, the possibility ofinfection due to contamination of the drainage bag is materiallydecreased. In this connection, it is to be appreciated that considerablediificulties have heretofore been experienced in the currently used opentype drainage arrangements. In current type open system drainage thepossibility of contamination is present due to the bag-tube juncturewhich is not permanent and usually open to air borne contamination. Inorder to empty the current bags, the tube must be removed and replacedeither in the same bag after emptying or in a new bag.

In either case, the tube end and bag interior have been exposed to airborne contamination.

The advantage is especially attributable to the permanent bonding of thedrainage tube to the receptacle so that it cannot be removed. Thejuncture at this point being permanent, contamination due to theinadequacies of the open system is eliminated. Also, it is apparent thatwith the present assembly, the burden on a nurse or other attendant willbe materially reduced, having in mind that the bulkcollection containerwill have a capacity such that it may be used to drain several bags. Ifdesired, the face of the receptacle 20 may be engraved or otherwisesuitably marked with indications of the volume, based upon cubiccentimeters, or otherwise. This may be helpful, in the case of a givenpatient, to both the physician and technician.

Thus, among others, the several objects of the invention as specificallyaforenoted are achieved. Obviously, numerous changes in construction andrearrangements of the parts may be resorted to without departing fromthe spirit of the invention as defined by the claims.
